Hyperloop undergoes successful test of high-speed propulsion system

Elon Musk's much-vaunted Hyperloop supersonic train system took a tentative step towards reality with its first public test of a track run of its propulsion system prototype in the Nevada desert. The company, which changed its name to Hyperloop One on Wednesday to coincide with the open-air propulsion test, has also closed an 80m series B funding round which included investment from the French national rail company, SNCF. When – and very much if – completed, the Hyperloop train would work by propelling a sled at high speeds through a vacuum-sealed tunnel, which its founder claims would be able make the journey from San Francisco to Los Angeles in just 30 minutes. The Nevada test represents a very early proof of concept; there are a vast number of hurdles that the developers of Hyperloop still have to clear if the technology is to become a reality. Hyperloop One also announced a series of other partnerships, including Deutsche Bahn Engineering & Consulting and the British engineering consultancy group Arup, who are currently working on London's Crossrail.
